AUTOMATIC SPRAY-VALVE.

Application filed April 28, 1909. Serial No. 492,785.

T 0 all whom it may concern:

Be it known that I, HARRY J. RICHTER, a

citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Automatic S ray- Valves, of which the following is a ful and correct specification, reference being had to the hereto accompanying sheet of drawings, forming a part hereof, and in which Figure 1 is a central longitudinal section, except a part of a central element shown in perspective. Fig. 2 shows Fig. 1 in a slightly modified form. Fig. 3 is a transverse section taken on the cutting plane 3 8 of Fig. 1. Fig. 4 is a transverse section of Fig. 2 taken on the cutting plane a a of Fig. 2. Fig. 5 shows Figs. 1 and 2 in plan view.

Like reference letters denote like parts throughout.

The object of my invention is to produce a low-priced and effective automatically acting spray-valve. To attain said desirable end I construct my said device in substantially the following manner, namely: I make a nozzle-holding, cylindrically bored, shell A adapted to be screwed onto a pipe. Said shell is provided with a coned nozzle-end. m of which the nozzle-mouth forms a valveseat a, and on said valve-seat is held a valve 0) which is provided with a long cylindrical stem (Z and for easier and more perfect construction of said shell and the nozzle the shell is screw-threaded, internally, at each end and into its discharging end is screwed a nozzle-piece m provided with a shouldered and screw-threaded neck 0 attached to the shell A, and within said neck is a valve-stem guide I) provided with radial arms extending to and integral with said neck. The free end of said valve-stem cl is screw-threaded into a radially armed nut 64 whose arms play freely in the smoothbored cylinder A and, thereby, form another guide for said valve-stem; and on said guide 6 stands a spiral expansion or compressible spring 00 which surrounds said valve-stem and pushes up the nut a and thus seats the valve '0 and holds it closed until adjusted resisting strength is overcome by an outward pressure Within said shell A, to which it yields gradually and then lets out a thin umbrella-like film of water.

In Fig. 2 the lower and fixed valve-stem guide 6 is integral with the shell A.

hat I claim is:

1. The combination with a cylindrically I bored shell provided with a. conically tapered valve-seated nozzle-end, a valve-stem guide at the base of said nozzle, of a valve, an end-threaded valve-stem a radially armed nut on said stem, and a spiral spring between said guide and nut said radial arms forming movable guides for the valve-stem.

2. The combination with a cylindrically bored shell provided with a conically tapered, valve-seated, shouldered and threaded nozzle-end having a valve-stem guide, of a valve, an end-threaded valve-stem, a radially armed nut on said stem, and a spiral spring between said guide and nut, said radial arms forming movable guides for the valve-stem.

3. The combination with a cylindrically bored shell provided with a valve-seated nozzle-end, said nozzle tapered toward a centrally placed valve-stem, a valve-stem guide at the base of said nozzle, of a valve, an end-threaded valve-stem, a radially armed nut on said stem and a spiral spring between said guide and nut.
